二熟耕作区是我国粮食生产的重点区域,其产量占全国总产量的53.2％。1985年以来该区粮食生产形势及生产格局发生了巨大变化,黄淮与江淮地区粮食总产量分别增长47.63％和61.67％,四川与西南地区粮食总产量增长43.76％和10.32％。二熟耕作区未来粮食增长的重点应放在黄淮与江淮地区,其技术对策为主攻高产田,大力抓好中低产田改造;选用优良品种,提高水肥利用效率,以提高综合效益,降低成本。
Second cropping area is the key area of grain production in our country, and its output accounts for 53.2% of the total output of the country. Since 1985, the grain production situation and production pattern have undergone tremendous changes in the region. The total grain output in Huanghuai and Jianghuai areas has increased by 47.63% and 61.67% respectively, while the total grain output in Sichuan and Southwest China has increased by 43.76% and 10.32% respectively. Second cropping area should focus on the future grain growth in the Huanghuai and Jianghuai areas, the technical measures to focus on high yield fields, vigorously grasp the transformation of low-yielding fields; selection of fine varieties, improve water and fertilizer use efficiency, in order to improve the overall efficiency and reduce costs .
